Rooftop Koreans

Est. 1992, the Rooftop Koreans made history as a hastily formed group of Korean-Americans who defended their businesses and livelihoods during the L.A. riots. Their numbers largely consisted of volunteers: mostly shop owners and whoever accepted the call to arms- friends, family, and community members alike. The LAPD had largely abandoned the Korean-American community in their greatest time of need (go ahead, look it up), leaving small business owners in Koreatown to essentially fend for themselves against opportunistic looters and thieves. Their spirit has left a profound mark on American small business owners to this day, representing a rallying cry of eternal vigilance against rabid mobs of looters and in more modern days, herds of alleged "anti-fascists" and "peaceful protestors".

Some of the most memorable imagery and live footage of the '92 riots captures the moments when Korean-Americans armed themselves with whatever firearms they could get their hands on and provided overwatch from the rooftops of their privately owned shops and markets (hence the name Rooftop Koreans).

It is worth noting every Korean male is required to provide 2 years of mandatory service in the Republic of Korea Armed Forces.
Give a Korean immigrant a life in the United States, and he'll be the proudest American of them all. But should you choose to burn his home and torch his livelihood, you'll have to deal with the feared Rooftop Koreans: an unstoppable community and force of nature, hailing from the eagle-screeching patriotism of the founding fathers of the U.S. of-fucking-A and the South Korean mainland.

korean sauce 

Korean sauce is a slang word meaning a "bad" pornhwa (it's not necessarily always pornhwas, sometimes it's manhwas as well). It is very similar to NTR or Netorare. It mainly implicates rape, incest, blackmail, cheating and all sorts of horrible things... It's for some reason often seen in the pornhwas nowadays (I don't know if Koreans likes this kind of thing). It's only mindless authors having nothing to do than rotting the poor souls of readers, it's the opposite of wholesome.
Scout: "Ain't liking this one, this crap is certified Korean sauce."
Reader: "Thanks a bunch! You saved me right there. Otherwise, I'd be rotting in Satan's horrible pit..."

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
